setting up Moeller VFD to chinese spindle

[routercnc]

CRACKED IT!

Read around more and found a thread about setting the base freq to 400Hz (this was for the Chinese VFDs). Tried this and success! On the previous screenshots A003 and A004 should both be 400Hz it would seem.

I'd kept the 2 poles as you suggested John, thanks for that. You mention base freq as 50Hz - it doesn't seem to like this, maybe that is for motors used on for lathes, drills etc rather than these Chinese Spindles?

Anyway, working now. When I press the green {I} button, then spindle quickly spools up to 50Hz (stays cools, sounds nice). I can then rotate the pot and send it all the way to 400Hz.

There are settings for this start freq and end freq (A061 and A062) which were 50Hz and 400Hz, which seem to be the ranges controlled by the pot.

I then set the accel and decel to 2 seconds (default was 10sec) and it all still works fine. Since I'll be using small tools, with low inertia, I wonder if the braking resistor was a waste of money!

Anyway, happy bunny

p.s. The VFD, mains filter, and spindle are on my computer desk (in the house) and are about 3" away from my LCD screen - there is no interference or lines on the screen which is an encouraging start. With the mains filter and screen motor cable it would seem to be doing something although the real test will be when it is back in the garage on the CNC machine.
